CUTTING DIE.

Application filed April 23,

This invention relates to improvements in cutting dies and moreparticularly to a the for employment in cutting gauntlet cufis from astrip of cloth or other material. As

such cuti's must be wider at their rear ends than at their front endswhere'they are united marginally to the gauntlets, the end edges must beout along non-parallel lines and heretofore there has been aconsiderablewaste of material resulting from this cutting operation. Therefore, itis the primary object of the present invention to provide a cutting dieby the use of which'gauntlet cuffs or blanks may be out from a strip ofmaterial without any appreciable waste.

One method of cutting gauntlet cuits from a strip of materialcontemplates the employment of a cutting blade reciprocating at a highrate of speed but by this method complieated' mechanism must be employedto move the blade or the material to effect the desired curvilinear cut.Therefore, itis another important object of the present invention toprovide a cutting die which may be mounted upon the head of any diepress of ordii'iary construction and which die will be soconstructed'that, in the operation of the press, and by rotating the diethrough one half a revolution after each cutting operation, cuii' blanksmay be cut from a strip of material. with accuracy and without anyappreciable waste of the material.

Another object of the invention is to so construct the die that it maybe readily adjusted to adapt it for cutting cuff blanks of diii'erentlengths.

in the accompanying drawings:

Figure 1 is aview in elevation illustrating the cutting die embodyingthe invention mounted upon the head of a die press of ordinaryconstruction.

Figure 2 is a perspective view of the die.

Figure 3 is a detail vertical sectional view taken substantially on theline 33 of Fig ure 2', looking in the direction indicated by the arrows.

, Figure 4: is a plan view illustrating schematically the manner inwhich gauntlet cufl' blanks are cut from a strip of material by the useof the die embodying the invention.

In Figure 1 of the drawings, the numeral 1 indicates in general the headof a die press of ordinary construction and 2 the bed block upon which,in accordance with the present invention, a strip of cloth is placed tobe oper ated upon by the die embodying the inven- 1926. Serial No.104,174.

tion, it being understood, that, in practice some means will be providedfor feeding the cloth to the press as the press is operated. he dieembodying the invention is indicated in general by the-inimeral 3 andthe same is mounted, in a manner to be presently explained, upon theunderside of the head 1 of the press and above the bed block 2.

Figure 3 of the drawings illustrates schematically the manner in whichgauntlet cuff blanksare to be cut from a continuous strip of cloth,through the employment of the die of the present invention and in thisfigure, the

numeral 41 indicates the blanks, each blank, when cut, being of a widthequal to the width of the strip of cloth from which it is produced andhaving curvilinear end edges in dicated by the numeral 5. These edgesare curvilinear for the reason that one longitudinal edge of the blankmust be longer than the other, which latter edge is to be stitched tothe wrist portion of the gauntlet, the cuff be ing of greater dimensionsat its unattached end than at its end which is attached to the gauntlet.Heretofore as previously explained, difliculty has been experienced incutting such blanks without a considerable waste of material and the dieembodying the invention is designed and operated in a manner to obviatethis waste.

The die comprises a pair of die members indicated in general by thenumeral 6 and a supporting plate which is indicated by the numeral 7.and said plate is providedcentrally with an opening 8 for the passagetherethrough of the cylindrical shank of a I supporting bolt indicatedby the numeral 9,

the bolt having a reduced threaded end 10 which is fitted into athreaded socket 11 formed in the under side of the head 1 of the press,the head 12 of the bolt serving to supportthe plate 7 so that it may berotated. Each die member 6 comprises a head 13 which is fiat and formednear its inner end with spacedopenings 141 for the passage therethroughof bolts 15 which fit adiustably in slots 16 formed in the ends of thesupporting plate 7, nuts 17 being threaded onto. the bolts andtightened. to bear against thcunder side 01 the said plate 7, it beingunderstood that in this manner. the heads 13 of the die members 6 areadjustably secured upon the upper side of the said plate 7. The slots 16in the plate 7 extend parallel to each other and it will be evident thatby loosening the nuts 17, the die members 6 may be adjusted outwardly orinwardlyso'as to adapt the die to cut blanks ot' diliierent lengths.

Each die member (5 further includes a blade 18 which is of arcuate formand extends downwardly "from the outer end of the respective head 13.the lower edge of the blade being sharpened to provide a cutting edgeindicated by the nun'ieral 19. This edge 19 is of curvilinear form toproduce the curvilinearend edges of thc blanks and inasmuch as eachblank is of greater length at one longitudinal edge than at the other.the cuttingedpgcs 19 are oppositely curved, that is to say, the cuttingedsres are eccentric to the pivotal center of the die or converge iromone side of the die to the other side thereof.

In the operation of the press and followin each cutting operation, thedie is rotated through one hundred and eighty. degrees so that, thestripof cloth is fed over the surf face of the bed block 2, thelongerlongitudi- .nal edges otthe blanks will be alternated as shown s-:hemat1cally in F1 ure f the drawings,,thereby effecting; aconsiderable saving in, the material.

It will be understood that the present invention is not concerned withthe manner in which the, strip of cloth is fed over the surface of thebed block 2, nor with any mechanlcal means which might lie-provided forautomatically or otherwise rotating the die, the invention residingprimarily in a rotatably supported or reversible die of the generalconstruction illustrated and de scribed. I

It will also be understood that while the pdie illustrated and describedis adiustable,

1 the plate being provided .with slots, cutting the die, maybeconsidered as comprising a head, of which the member 13 and plate 7constitute component parts, and blades extending from the head andhaving oppositely curved cutting edges, for it the adjustable feature isnot desired, the meinbers 1.3 might be integrally formed or they mightbe secured .to,.the plate without the provision of means for adjustment.

Having thus described the invention, what I claim is:

1. A cutting die comprising a supporting plate, means forsupportinn',the plae for plate-and adj ustably securing the heads to the plate. 7

3. A cuttlnn'die comprising a head, means for supporting the head forrotative reversal,

and arcuate blades extending downwardly from. the head eccentric to thecenter of rotation of the headand having their concave sides presentedtoward eachother, the lower edges of the blades constituting theircutting edges.

In testimony whereof-I aiiix my signature.
